`Befaimovmanni, y y o arcitizen of the 4vUnited States of America, and a resident'of Bogota,` inthecounty'of Bergen yand State of New Jersey,have 1nventeda new andr Improved Guard Rail vfor Station Platforms, of which the following4 isa full,l clear, andexactdescription. f i, This invention has relation to safety. Ide,- vices for L station platforms and 'a1msfor i one of its principal objectsl to Iprovide means i adjacent the edge of subway,elevated yor other railway' platforms for preventingacci# dental. forcing of waitingv passengers over theedgefand Ainithepath of moving trams.

At the present time due to congested traino conditions .in the lar er citiesvelevated and subway platforms `w ihare disposed. in

the, sameplanewwiththe i train floors and platforms, presenta dangerous situation to the traveling public when the platormsbe-j unobstructed ingress and. egress adjacent come over-crowdedandlthe possibilit v of forcing passengers ad'acentf the edge oy the platform into the pat of inoving ,trains It is therefore ari/object ofthe present 1nedge of af'stati'on. platform which extends throughout the length ythereof and to4` provide movable sections in said -railing 4connected with means operable-.by the trains pulling into` a station for movingsaid movable sections lto an iout-of-the-way position so v`thatthe lpassengers lwillhave freefand the doorwaysoftheftrain. yi. f.

The inventionvv furthermore comprehends an Lapparatus offthefv` character lset forth which is comparatively simple" in its conhhighlyyyeilicient4 in `its purpose and. which struction 't and imodepf; operation, which is may bereadilyinstalled at a minimum expanying drawings, itfbeing understood4 that HENRYy McMANuaf [Animationraiedrneniber e.y y19124. semina. 754,819.

Int/he drawin e V ,-Figurefl is a lfragmentary View partly in section and partly in elevation .illustrating the safetyguard means installed on a station platform and showing respectivelyin full and l dotted lines the closed and open conditionof the'vv same. e

A Fig. 2 is a fragmentary vplan view thereof illustrating thetrain actuating means in its active `and inactive positions in full and` dotted lines.

Referring .to the drawings ,by characters of.l reference 10k designates a station platform of the type which is disposed in the same planefwith the'car floorsand platforms and in; whichthe road-bed is in a lower or sunkenfplane,y In'accordance with the pres,- entinvention the platform' is provided with a railing 1 1` approximately waisthigh which islsupported adjacent` the edge of the platform kby standards or uprights 12.` The or piston 15 movable in acylinder 16 which More specifically Lthe- :invention fjcoinprefk ard railing having vertically movf,

cylinder v,is mounted vertically of thel plat-` form and adjacent the edge thereof and.: approximately vmidway. between the vspaced.

y endsof .the stationary guard rail sections l1.

rlrhe movablel guard rail sections 18 are vertically apertured adjacent their opposite ends as at' 1'( to receive the vertical guide rods 18 which areconnected to the platform and if desiredfto an,4 overhead support or ceiling 19. The lower end of the ,cylinder 16 has communicating therewith a fluid conduit 20 whichlleadsto a suitable source of fluid supply such as compressed air or the like. i

The conduit 20 has arranged therein a valve 21; of any, approved type the core-of which is connectediwith an actuating arm 22 whereby when the armi is swung 1n onei direction communication is established through the conduit;y from the fluid supplyv to the cylinder 1.6 andgyvhen moved to another position said communication l is cut olf.
